INTRODUCTION

The present teaching relates to methods and systems for associatinginformation with carriers for supporting biological reagents. During themanufacture and use of biological reagents, the reagents are typicallycoded and labeled in order to keep track of them. Conventional systemsuse bar codes to identify carriers containing reagents to be processedby analytical instrumentation. Bar codes, however, require printing andapplication of a bar code label to carriers for the biological reagents.At some later time the bar code is read by either a hand-held bar codescanner or by an automated bar-code scanner controlled by theinstrumentation to track the reagents as they are processed.

To read a label or a barcode, however, requires an optical path to thebarcode, which can be inconvenient and problematic, for example if theindicia to be read are located inside of an instrument. In the pastthese problems have been addressed by forming windows in the instrumentsor carriers to provide an optical path to the labels. Such windows cancomplicate the design of instruments and carriers and depending on theconfiguration and design of a particular window, the optical path can bedistorted, resulting in optical reading and scanning problems. Furtherreading problems can result from printing inconsistencies and anymaterial that covers the bar code, such as frost in a refrigerator.

Further, if information needs to be added to a label associated with aparticular sample, physical access is required to print the additionalinformation to the label. Moreover, only a limited amount of informationcan be printed on a label associated with a carrier due to label spacelimitations. When using bar codes, 1-D and 2-D bar codes are limited asto how much information can be printed in a given amount of space by thevisual resolution between marks. Therefore, typically a printed carriernumber or identifier is used as an index into a database of informationregarding the carrier or the contents of the carrier. The database wastypically provided on a separate CDROM or other removablemachine-readable medium. However, it can be inconvenient to associatethe information on particular CDROM with a particular carrier.

Vincogen Corporation of Trevose, Pa. purports to have filed U.S. patentapplication Ser. No. 10/396,269, on using RFID technology in connectionwith biochips to provide an identifier number for such biochips.However, the Vincogen product fails to address the above-identifieddeficiencies of existing methods and systems.

Accordingly, systems and methods are needed that provide for the readingfrom and writing to carriers for biological reagents without requiringan optical path or direct physical access to the carriers. Moreover,there is need for storing greater amounts of information than can bewritten on a conventional label.

DESCRIPTION OF VARIOUS EMBODIMENTS

Reference will now be made in detail to some embodiments, examples ofwhich are illustrated in the accompanying drawings. Wherever possible,the same reference numbers are used throughout the drawings to refer tothe same or like parts.

Radio Frequency Identification (“RFID”) provides a convenient mechanismfor identifying and detecting objects using wireless electro-magneticsignals. A basic RFID system has at least one RFID reader and at leastone RFID tag. Typically, RFID readers can include a coil or antenna andcircuitry to transmit and receive signals with the coil or antenna. AnRFID tag also includes a coil or antenna and some information that canbe read by an RFID reader.

The RFID reader antenna generates an electromagnetic field, therebytransferring energy to the tag. Depending on the design of the tag, aportion of the energy transferred to the tag will be reflected to thereader so as to provide information about the tag back to the reader.Some RFID systems can be used to read and optionally write data to andfrom the RFID tag. RFID readers can generate signals spanning distancesfrom less than one inch to more than 100 feet depending on frequency andpower of the signals generated at the RFID reader antenna.

Typically, RFID tags are categorized as either active or passive. ActiveRFID tags are powered by an internal battery and are typicallyread/write, i.e., tag data can be rewritten and/or modified. An activetag's memory size varies according to application requirements; somesystems operate with up to 1 MB of memory.

Passive RFID tags operate without a separate external power source andobtain operating power generated from the reader. Passive tags areconsequently typically lighter than active tags, less expensive, andoffer a long operational lifetime. Passive tags typically have shorterread ranges than active tags and require a higher-powered reader.Read-only tags are typically passive and can be programmed with a uniqueset of data (usually 32 to 128 bits) that is typically predetermined atthe time of manufacture of the tag. It is understood that passiveread/write tags can also be employed consistent with the presentteachings.

The term “RFID tag” as used herein refers to either an active or passiveRFID tag that contains information. The RFID tag can be read only orread/write, and the information associated with the RFID tag can behard-coded into the RFID tag at the time of manufacture or at some latertime, or the RFID tag can contain information that is written to theRFID tag throughout its lifetime.

The term “RFID reader” as used herein includes RFID devices that canread information from and/or write information into an RFID tag.

The term “carrier” as used herein refers to a structure for directly orindirectly supporting a biological reagent. Examples of carriers includereaction plates, tubes, tube carriers, surface plasmon resonance arrays,slides, conical low-volume tubes, microfluidic cards, microarraycartridges, microarrays, and other types of containers for supportingbiological reagents.

The term “biological reagent” as used herein refers to a biologicalmaterial used for various biological analyses such as detecting,examining, and/or measuring information from biological samples.Biological analyses can include reactions such as polymerase chainreaction (PCR), ligase chain reaction, antibody binding reaction,oligonucleotide ligation assays, and hybridization assays. Examples ofbiological reagents include nucleic acids, primers, probes, and otherbiological reagents, which can be used in performing various biologicalassays. “Nucleic acid” as used herein refers to nucleotides,oligonucleotides, DNA, RNA, PNA, etc. as these terms are understood bythose skilled in the art of genomics.

The term “information” as used herein refers to data that can be storedelectronically in the RFID tag and can be retrieved to be used asmachine readable or human readable data for processing the biologicalreagent and/or carrier.

The term “identification information” as used herein refers toinformation on an RFID tag that can be used to uniquely identify aparticular carrier or biological reagent or to distinguish the carrieror biological reagent from other carriers or biological reagents. Forexample, identification can relate a particular assay prepared for aparticular customer.

The term “supplemental information” as used herein refers to descriptiveinformation about a carrier or its contents, including certainbiological reagents. Examples of supplemental information includenucleic acid sequence information and annotated information regardingexperiments performed with various biological reagents.

The term “rights information” as used herein refers to authorizationinformation for carriers or biological reagents, such as informationregarding whether a particular licensee has a valid license to use aparticular carrier or biological reagent, including a number of timesthe licensee is permitted to use the particular carrier or biologicalreagent in a particular assay. Rights information can also includevalidation information regarding whether a particular carrier orbiological reagent has been subject to a recall or has otherwise becomeunsuitable or unauthorized for use.

The term “genealogy information” as used herein refers to informationregarding the derivation of a biological reagent, including for examplean identification of an original sample from which it was derived or thenumber of generations removed it is from an original sample.

The term “traveler information” as used herein refers to informationregarding a carrier or a biological reagent contained as operations areperformed on that carrier or biological reagent for example duringmanufacture of the biological reagent or while an assay is beingperformed on the biological reagent.

FIG. 1 illustrates a perspective view from above of a reaction plate 100having a plurality of reaction wells 102 and exemplary locations 110,112, 114, and 120 for RFID tags. It is understood that exemplarylocation 110 for the RFID tag, for example, can be positioned on theexterior of the reaction plate 100 in any convenient location that willpermit appropriate antenna geometry and accommodate the necessarypassive or active RFID circuitry necessary for proper operation of theRFID tag. For example, RFID tags 110 and 112 are shown as boxes placedin the margins of the reaction plate 110 on an upper surface 116 of thereaction plate 100. Adhesive application of an RFID tag to the surface116 of the reaction plate 100 can advantageously permit standardconsumables, such as reaction plate 100 to be manufactured and/oracquired independently from the RFID tags. Alternatively, RFID tag 120,illustrated in broken lines, can be embedded in the reaction plate 100,for example during a plastic injection molding or a blow moldingmanufacturing process. Trays and microcards are typically constructed ofpolypropylene so as to be compatible with PCR thermal cycling. Othercarriers that provide transport containers as opposed to reactioncontainers can be made of harder plastics e.g. Lexan® (GeneralElectric). FIG. 1 illustrates a 96-well reaction plate. As illustratedin FIG. 7, other reaction plates such as 386-well reaction plates arecontemplated by the present teachings.

FIG. 2 illustrates an underside perspective view of the reaction plate100 showing the undersides 204 of a plurality of reaction wells and atleast one RFID tag 202 affixed to an underside portion of the reactionplate. As shown in FIG. 2, the RFID tags can be placed on the undersideof the carrier as shown in connection with RFID tags 202 and 206, whichare shown to be applied to the surface 216 of the reaction plate 100.Alternatively, an RFID tag 208 can be applied to a side surface of thereaction plate 100. As set forth in connection with FIG. 1, in variousembodiments, the RFID tags can, for example, be adhesively applied toconsumables, such as on the reaction plate 100. However, the RFID tagscan also be embedded in the body of the consumables, for example duringa plastic injection molding or a blow molding manufacturing process. Tofacilitate a transition from barcodes to RFID, both barcodes (not shown)and RFID tags can be present on consumables consistent with the presentteachings, such as the reaction plate 100.

According to various embodiments, the reaction plates contain biologicalreagents such as nucleic acid materials, primers, and probes, which areused in connection with various biological assays to determine, forexample a genetic sequence of a particular sample. In variousembodiments, separate RFID tags on the plate are associated with groupsof wells within the reaction plate. In other embodiments, an RFID tag isassociated with a single well in the reaction plate 100. In otherembodiments, a single RFID tag is associated with the entire reactionplate, with the RFID tag containing information regarding each of thewells and the contents and history of the contents of each of the well.In such embodiments, a read/write RFID tag containing a substantialamount of memory can include, for example, identification, supplemental,and/or rights information about the contents of the wells 102 (of FIG.1).

Invarious embodiments, RFID tags in or on the tubes contain informationregarding nucleic acid samples, primers, or probes contained in each ofthe tubes. In such embodiments information regarding the geneticsequences of the nucleic acids, for example, are stored in the RFIDtags. Further, annotated information regarding the biological reagentscan be stored in the RFID tags, for example, information regardingresults of experiments already performed with the biological reagents.

According to various embodiments, no read/write RFID tag is directlycoupled to a particular tube. Rather, the tube bears a simplified RFIDtag or optical indicia that provides, for example, row and columninformation for the tube's position in the tube carrier 400. Then, forexample, information regarding the contents of tubes can be stored in amore complex RFID tag that is affixed to or embedded into the tubecarrier 400, either at the lid 402 or at the carrier base 404.Alternatively, additional information can be stored on a CDROM or otherremovable medium and associated with each tube, for example, based on aunique identifier on the RFID tag associated with the tube or tubecarrier.

Invarious embodiments the instruments are coupled to a network (see e.g.FIG. 11) that allows the instruments to communicate over public andprivate networks with computer systems that are operated by or on behalfof the producers and/or licensors of the biological reagents. In variousembodiments, reagent licenses can provide for the use of licensedbiological reagents for a particular biological analysis on onlylicensed instruments. In various embodiments, instrument licenses canprovide for the use of licensed instruments to carry out a particularbiological analysis with only licensed reagents. Accordingly, aninstrument can authenticate a biological reagent based on, for example,a digital signature contained in the RFID tag associated with aparticular consumable, if a particular user has a valid license. INvarious embodiments, the RFID tags can also be programmed to provide aone time use such that biological reagents cannot be refilled with foruse with the same authentication.

According to various embodiments, when an RFID tag is read by aninstrument that has access to a data network that includes a connectionto information regarding biological reagent recall information, theinstrument can perform a database lookup to determine whether thebiological reagent has been subject to a recall. The recall informationand an optional last recall check date and/or timestamp can be writtento the RFID tag. In various embodiments, a recall database lookup isperformed each time before a biological reagent is utilized in an assayor other test such as, for example a clinical diagnostic procedure.

According to various embodiments, external displays are provided todisplay information regarding the biological reagent contents of aconsumable when the biological reagent is inside of an instrument orother container, such as a refrigerator. For example when a microarrayis contained within its microarray cartridge, an RFID reader can readthe identification information from the microarray and display it on ahuman readable interface, such as a computer terminal, LCD, or othertype of display.
